[Spits] Weird engine idle

[mark.jones at exxonmobil.com]

Doesn't sound like ignition to me either.

Twin HS4s for carburettors. I adjusted the mixture a couple weeks before
the problem, probably have a couple hundred miles on them since adjusting
the mixture,  The car was over in the Michigan when this happened and had
several tanks of MI gas put in it.  A friend, who was travelling with us in
an MGB, noticed his fuel filter was very discoloured, I wonder if something
has happened to mine as well?  Replacing the fuel filter is actually the
next thing I was thinking of trying, got a spare sitting on the work bench,
waiting for me to get home.

It doesn't really sound like an ignition problem...
What is your carburetion system?
Anything change there recently?
